How to fix 504 error on AWS CloudFront

+2 votes

I created a CloudFront distribution, linked it to the load balancer that has my ELB EC2 instance as target. My ELB url is working just fine, and is showing my Angular app.

But I don't know why my Cloudfront URL gets me a 504 error. I would immensely appreciate any help.

This usually happens if it couldn't either establish a TCP connection or the HTTP first-byte response took more then what was configured in Origin read/response timeout.

To troubleshoot HTTP 504 errors, check the configurations on your firewall, security groups, and origin server to identify the source of the errors.

By default, CloudFront allows you to keep the origin connection open for 30 seconds. If your applications need more than 30 seconds to process and then return a response, then CloudFront returns an HTTP 504 error.

Hope this helps!
